This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X160-50, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 110 to 160 mm. This model is discontinued — the direct replacement is the MBLJ25X160-50.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50
The AirTAC MALJ25X160-50 is a discontinued double-acting mini cylinder with a 50 mm rear adjustable stroke stopper, yielding a usable extension window of 110-160 mm. The direct replacement is the MBLJ25X160-50, matching the 25 mm bore, 160 mm stroke, G1/8 port, and mounting footprint exactly.
This legacy unit features threaded covers and a fixed rubber bumper. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. The MBLJ upgrade switches to a riveted rolling-packed body and, if you ever need sensing, uses modern CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M reed sensors. Remember, the rear adjuster sets the end position but does not hold the load without live air pressure.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50 Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X160-50 |
| Bore size | Ø25 mm |
| Stroke | 160 mm |
| Adjustable window | 110 – 160 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ25X160-50 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ25X160-50 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50 Is Used
Carton Flap Folder
Adjust the 25 mm bore's reach on the fly to tuck varying corrugated carton minor flaps, ensuring the 206 N pull retracts the folding arm cleanly at different box heights.
Pneumatic Press Depth Stop
Set the rear stopper to 130 mm to control bearing seating depth in a small manual press, preventing over-travel using the 50 kgf max force without swapping the cylinder body.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50 with MBLJ25X160-50
To replace the MALJ25X160-50, order the exact direct replacement MBLJ25X160-50. Confirm the 25 mm bore, 160 mm stroke, 50 mm adjust code, G1/8 PT port, and FA/LB mounting (no back cover or SDB). Since this SKU has no magnet, you lose sensing; moving to an MBLJ-S variant enables CMSG/DMSG/EMSG sensors. The rear adjuster is a travel stop, not a mechanical lock.
At 160 mm stroke, prevent rod bending by minimizing side loads and guiding the load rigidly.
Upgrade checklist
- ✓ Order the MBLJ25X160-50 (same bore/stroke/adjust)
- ✓ Same 110–160 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ25X160-50 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-50 FAQ
Yes, the MALJ25X160-50 is discontinued. The direct replacement is the MBLJ25X160-50, matching the 25 mm bore, 160 mm stroke, 50 mm adjuster, G1/8 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design instead of threaded covers.
The -50 adjuster trims up to 50 mm at the rear, giving a 110-160 mm usable window. The adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure.
